GRUB 2.02 will be the next major update for this widely-used, open-source boot-loader. GRUB 2.02 is currently up to a beta state with GRUB 2.02 Beta 3 being the newest development milestone from just two weeks ago. This will be the first major update since GRUB 2.00 was released four years ago and the recent third beta has come two years after the second beta. Below is a look at some of the highlights for GRUB 2.02.
On the file-system front there is Coreboot CBFS support, ZFS features and LZ4 support, LVM RAID1 support, XFS v5 format support, compressed HFS+ support, and other improvements.
Some of the other GRUB 2.02 work includes Coreboot frame-buffer support, new graphics menu options, improved FreeDOS direct loading support, multiboot2 work, new Yeelong hardware support, support for Microsoft Hyper-V Gen2 platforms, a new Xen loader on ARM64, a new boot time analysis framework, native MingW support, experimental Clang compiler support, and more.
